Reneta Bonar filed the lawsuit in a California federal court on behalf of the class saying she and many others have been deceived by claims that SkinnyGirl contains no preservatives. In fact, as the Whole Foods scandal revealed, the drink contains a preservative called sodium benzoate.

The suit says that Beam Global Spirits and Frankel "engage in a corrective advertising campaign" and requests pay out for unspecified damages.

Beam Global Spirits issued a statement which says, "In today's litigious society, nothing is surprising. The litigation filed in relation to the labeling of Skinnygirl Margarita is frivolous. We will defend our case vigorously, and we are fully confident we will prevail."

Bethenny Frankel has so far remained mum on the pending litigation. SheKnows has located Reneta Bonar and is awaiting comment.
